The present invention relates to a resistance plate structure of an energy generation apparatus, and more particularly, to a resistance plate structure of an energy generation apparatus which can generate electricity by means of the movement of fluid when a rotary body is rotated by resistance generated in the resistance plate by fluid.

BACKGROUND ART

In general, wind power generation and solar energy generation are used as methods for producing electricity, in addition to waterpower generation, tidal power generation, thermal power generation, and nuclear power generation. From among these, facilities for thermal power generation and nuclear power generation require huge power energy, high technology, human resources, high-priced high tech equipment to be driven, and also, have problems that they have adverse effects of producing a large amount of environmental pollutant which may lead to an environmental disaster, in addition to very high installation and maintenance costs.

Accordingly, in Korea, there is a growing interest in development of eco-friendly and low-carbon new regeneration green energy using wind power or tidal power by taking into account geographical conditions of Korea, which is surrounded by the ocean on three sides and consists mostly of mountainous regions where wind is easy to travel. The most frequently installed/used typical wind power generation apparatus has a structure, known as a propeller type rotation structure, including a power transmission unit which is mounted at the upper end of a vertically installed tower, and a single rotary wing which is vertically mounted on one side of the power transmission unit to face the blowing direction of wind, and which has about 3 or 4 blades arranged radially at equal angle intervals within a predetermined diameter range. A related-art wind power generator of this structure has an inefficient structure in which a single rotary wing device is disposed at the upper end of a tower in a vertical direction like vanes of a fan. Therefore, only a small amount of power is generated according to the rotation of the single rotation wing, and a large number of structures are required in an enormously large place to increase the amount of generated power. Therefore, there is a limit to power generation compared to the enormous installation place and investment costs. In addition, in related-art power generation methods, a regular position is determined only by power pushing a resistance plate according to the flow of water, but there is a problem that pushing power is not well utilized when the resistance plate is heavy.

Rather, the exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those of ordinary skill in the art, and the present invention is defined by claims. Like reference numerals used throughout the specification indicate like elements.

Hereinafter, the present invention will be described with reference to the drawings for describing a resistance plate structure of an energy generation apparatus according to exemplary embodiments of the present invention.

First, the resistance plate structure of the energy generation apparatus according to the present invention is rotated according to the direction of a fluid flow to generate electricity.

Referring to FIGS. 1 to 4, the resistance plate structure of the energy generation apparatus according to the present invention includes a housing 110, a rotary body 120, a rotary support bar 130, a resistance plate 140, and an angle restriction part 150.

The housing 110 has a power generator provided therein.

The rotary body 120 is rotatably coupled to the housing 110.

The rotary support bar 130 has a locking groove 131 recessed along the circumference of the outer surface thereof to be inserted into a fixing groove 141 and to face a connection hole 144.

The resistance plate 140 has the fixing groove 141 recessed inwards from one side surface thereof to allow the rotatory support bar 130 to be rotatably inserted thereinto, and generates resistance by means of gas or fluid.

That is, in the resistance plate structure of the energy generation apparatus according to the present invention, the rotary body 120 is rotated by the resistance force generated by the resistance plate 140, and the power generator generates energy by means of the rotational force of the rotating rotary body 120.

In addition, the rotary support bar 130 includes a first bearing 132 and a second bearing 133.

The first bearing 132 is formed on the rotary support bar 130 facing one side surface of the resistance plate 140.

The second bearing 133 is formed at one end of the rotary support bar 130.

That is, the first bearing 132 and the second bearing 133 are formed on the rotary support bar 130, thereby facilitating the rotation of the resistance plate 140.

In this case, the first bearing 132 formed on the middle of the rotary support bar 130 is larger than the second bearing 133 formed at one end of the rotary support bar 130. More preferably, the outer diameter of the first bearing 132 may be the same as the outer diameter of a protrusion 151 of the rotary support bar 130, and the outer diameter of the second bearing 133 may be the same as the inner diameter of the fixing groove 141, such that the second bearing 133 can be inserted into the fixing groove 141 of the resistance plate 140.

In this case, a plurality of resistance plates 140 may be provided on the rotary support bar 130.

The angle restriction part 150 rotatably couples the resistance plate 140 to the rotary support bar 130, but couples to restrict the range of a rotation angle of the resistance plate 140, such that the resistance plate 140 is in a vertical state in a forward direction in which the gas or fluid moves so as to generate resistance, and the resistance plate 140 is in a horizontal state in a reverse direction so as not to generate resistance.

In addition, the angle restriction part 150 includes the protrusion 151 and a clearance groove 153.

The protrusion 151 protrudes from the outer surface of the rotary support bar 130. In this case, the upper outer surface of the protrusion 151 is referred to as a first outer surface, and the lower outer surface is referred to as a second outer surface.

The clearance groove 153 is formed to be recessed from one side of the inner circumference of the fixing groove 141 to have a larger radius than that of the fixing groove 141, and has locking protrusions 152 formed on both ends thereof, and the protrusion 151 is inserted into the clearance groove 153. In this case, the locking protrusion 152 formed on the upper side of the clearance groove 153 is referred to as a first locking protrusion, and the locking protrusion 152 formed on the lower side is referred to a second locking protrusion.

That is, when the resistance plate 140 is rotated by gas or fluid, the locking protrusion 152 of the clearance groove 153 is caught by the protrusion 151 and the rotation of the resistance plate 140 is restricted, such that the resistance plate 140 is in the vertical state or the horizontal state according to the moving direction of the gas or fluid.

In other words, when the resistance plate 140 is in the vertical state, the first outer surface of the protrusion 151 and the first locking protrusion of the clearance groove 153 are brought into contact with each other, and, when the resistance plate 140 is in the horizontal state, the second outer surface of the protrusion 151 and the second locking protrusion of the clearance groove 153 are brought into contact with each other.

In this case, it is preferable that an angle between the locking protrusions 152 of the clearance groove 153 of the resistance plate 140 is greater than 90° and smaller than 180°.

In addition, the outer surface of the protrusion 151 of the rotary support bar 130 and the inner surface of the clearance groove 153 of the resistance plate 140 are formed to be parallel with each other so as to be brought into surface contact with each other when the resistance plate 140 is rotated.

Accordingly, the rotation angle of the resistance plate 140 between in the vertical state and in the horizontal state is smaller than 90°. When the resistance plate 140 is in the horizontal state, the second locking protrusion 152 is caught by the second outer surface of the protrusion 151, such that a minimum resistance angle is formed with respect to the horizontal plane. When the end surface of the rotary support bar 130 faces the gas or fluid in the forward direction, resistance is generated by the minimum resistance angle and the resistance plate 140 is rotated about the rotary body 120 and thereby enters the vertical state.

In addition, the resistance plate 140 is formed in a plate shape and the outer surface of the portion where the fixing groove 141 is formed bulges, and the resistance plate 140 includes an upper resistance part 142 and a lower resistance part 143 protruding upward and downward with reference to the fixing groove 141, respectively.

In this case, preferably, one of the lengths of the upper resistance part 142 and the lower resistance part 143 may be longer than the other one, and the weight of the lower resistance part 143 may be heavier than the weight of the upper resistance part 142. More preferably, the length of the upper resistance part 142 may be longer than the protruding length of the lower resistance part 143, and the weight of the upper resistance part 142 is lighter than the weight of the lower resistance part 143.

That is, when the rotary body 120 is rotated facing the forward direction of the gas or fluid, that is, the advancing direction, the resistance plate 140 is in the vertical state so as to generate resistance, and, when the rotary body 120 is rotated facing the reverse direction, the resistance plate 140 is in the horizontal stat so as not to generate resistance. In other words, the resistance plate 140 can be rotated about the rotary support bar 130 sensitively according to the flow direction of the gas or fluid.

In addition, the resistance plate 140 may have the connection hole 144 formed on the outer surface thereof to penetrate with the fixing groove 141.

In this case, the rotary support bar 130 may have the locking groove 131 recessed along the circumference of the outer surface thereof to be inserted into the fixing groove 141 and to face the connection hole 144.

In addition, the resistance plate structure of the energy generation apparatus according to the present invention may further include a separation prevention pin 160.

The separation prevention pin 160 is inserted into the connection hole 144 and has its end locked into the locking groove 131, and thereby prevents the rotary support bar 130 from being separated from the fixing groove 141.

That is, the resistance plate 140 is rotatable about the rotary support bar 130 by means of the gas or fluid, and simultaneously, is not separated from the rotary support bar 130 by the separation prevention pin 160. In addition, when the resistance plate 140 is rotated, the end of the separation prevention pin 160 is rotated integrally with the resistance plate 140 along the locking groove 131 which is recessed along the circumference of the outer surface.

The resistance plate structure of the energy generation apparatus according to the present invention may further include an angle adjustment part 170.

The angle adjustment part 170 is coupled to one or more of both side surfaces of the protrusion 151 to adjust angles formed by both side surfaces of the protrusion 151 and spaced from each other.

In addition, a plurality of angle adjustment parts 170 may be coupled to the first outer surface or the second outer surface of the protrusion 151.

Accordingly, the range of the rotation angle of the resistance plate 140 in the vertical state and the horizontal state is adjusted according to the spaced angles which are formed by both side surfaces of the protrusion 151 and are adjusted by the angle adjustment part 170.

In addition, the angle adjustment part 170 includes a length adjustment bar 171, a length adjustment member 172, and an angle adjustment member 173.

The length adjustment bar 171 is inserted into one side surface of the protrusion 151 and fixed to have an adjustable length protruding to the outside.

In this case, the length adjustment bar 171 is inserted into and fixed to one side surface of the protrusion 151 in a screwing method.

The length adjustment member 172 is coupled to the outer circumference surface of the length adjustment bar 171 to allow the length adjustment bar 171 to protrude from one side surface of the protrusion 151 toward the outside or to be inserted into the protrusion 151 according to the rotation.

In this case, the length adjustment member 172 is coupled to the length adjustment bar 171 in a screwing method to adjust the length of the length adjustment bar 171 protruding from one side surface of the protrusion 151 and inserted thereinto according to the rotation.

The angle adjustment member 173 is coupled to the end of the length adjustment bar 171.

In this case, it is preferable that the outer surface of the angle adjustment member 173 and the locking protrusion 152 of the clearance groove 153 of the resistance plate 140 face each other and are parallel with each other.

That is, according to the length of the length adjustment bar 171 which protrudes toward the outside of the first outer surface or the second outer surface of the protrusion 151 or is inserted thereinto by the length adjustment member 172, a distance between the first outer surface or the second outer surface of the protrusion 151 and the angle adjustment member 173 increases or is reduced, such that the range of the rotation angle of the resistance plate 140 rotated about the rotary support bar 130 is adjusted.

Accordingly, the resistance plate structure of the energy generation apparatus of the present invention can control the resistance force generated when the resistance plate 140 is in the vertical state, and accordingly, can control the rotation speed of the rotary body 120, and also, can prevent an overload of the power generator, such that the maintenance and management can be easily performed and the cost for maintenance and management can be reduced.
